I am Legend by Richard Matheson
Robert Neville is the last man in Los Angeles California. By day he roams the city gathering food and supplies to prepare himself for night, when vampires surround and attack his home.
A few years before, a germ had spread, turning everyone into the living dead: Neville had to bury his wife, twice. Nightly, Neville's old neighboor and carpool buddy, now walking dead, taunts him to come outside.
Written in the 1950s, and set in the 1970s, this novel is said to have launched the genre of post-apocalyptic fiction, and clearly influenced movie classics like "The Night of the Living Dead." It is also an intelligent, taut, creepy novel, that fully explores Neville's psychological highs and lows as he faces the end of human civilization.
